"As I was walking through a variety store, I stopped at the pet department to look at some parakeets. In one cage a green bird lay on his back, one foot hooked oddly into the cage wire. I was about to alert the saleswoman to the bird's plight when I noticed a sign taped to the cage: 'No, I am not sick. No, I am not dead. No, my leg is not stuck in the cage. I just like to sleep this way.'"
